A pair of arcuate shaped spring arms 14rand 15 respectively are securedat diametrically opposite sides of the crank shaft 13, on the outer sideof the crank case. These arms are secured by one of their ends to thecase, while their opposite end portions are disposed outwardly of thecase, in the manner shown in the drawings. These arms are arranged in'acircular manner. with the outwardly disposed free end portions toproject in the same direction.

Normally the shank 9 extends upwardly from the collar 7 l Vhen it isdesired to put the engine in operation, the operator takes hold of thehandle and through the medium of the connection illustrated moves theshank 9 to the position shown in Figure 1, the said movement of thehandle'6 being forward, and the said posiion of the shank 9 being thecrank engaging position. Incident to the said movement of the shank 9said shank 9 is engaged and moved by the arm 15, Figure 3, which bringsabout engagement of the ratchet on thecollar 7 with the ratchet on theshaft B. Thereupon the operator pulls the handle 6 rearwardly to startthe engine, and on starting of the engine the arm 14 will co-act withthe shank 9 and 7 from the shaft B.

The rod 4 is disconnected from the shank 9, as before described, inorder that a drive belt may be put on or removed from the drive pulleyon the shaft'B for the transmission of motion to some apparatus to beactuated by the engine.

It is to be understood that certain changes in the specific shape, sizeand materials may be resorted to, without departing from the spirit ofthe invention or the scope of the ap pended claims. 7

Having described this invention, What is claimed as new is:

1. Starting means for a tractor having a rear wheel fender and alsohaving an internal combustion engine with a shaft on which is a ratchet,comprising 'a bearing on said fender, a transverse rock shaft in saidbearing and equipped with arms, a bar pivotally connected to andextending rearwardly from one of said arms and disposed above saidfender, a rod pivotally connected to and eX- tending downwardly from theother of-said arms, a collar loose on said engine shaft and having aratchet opposed to that of the shaft and also having a shank pivotallyconnected to said rod, and arms mounted adjacent to the engine shaft formaking and breaking connection between the collar and the engine shaft;one of said arms being adapted to enthereby disengage the collar ward onupward and rearward movement of the shank.

2. Starting. means for a tractor comprising an internal combustionengine having a shaft on which is a ratchet, including in combination acollar loose on said engine shaft and having a ratchet opposed to thatof the shaft and also having a shank, and arms mounted adjacent to theengine shaft for making and breaking connection between the collar andthe engine shaft; one of said arms being adapted to engage and move theshank laterally inward on downward and forward movement of the shank,and the other arm being adapted to engage and move the shank laterallyoutward on upward and rearward movement of the shank.

In testimony whereof I aflix my signature.
